A work device including a cover provided on a base to form a work space between the cover and the base; a linear motor disposed in the work space having an extended stator and a movable element moving along the stator in a transfer direction; and a work executing section provided on the movable element to execute a predetermined work; wherein the movable element includes: a heat-dissipating section to dissipate heat generated from a constituent member to air, the constituent member constituting at least one of the movable element and the work executing section; a duct, covering the heat-dissipating section, having an intake port and an exhaust port; and a blower to blow the air from the intake port of to the exhaust port.

Work device with air-cooled linear motor

A component mounting machine that performs mounting of components by moving a mounting head attached to slide using linear motor, stator of the linear motor that is forms of magnets arranged side by side is arranged on base, movable element is fixed to a slide so as to pass through the stator, and bracket for holding a portion of wires for supplying power to the linear motor and wire protector is fixed to the movable element. Since the bracket is located at a position close to the axis line of the movable element, the rotational moment acting on the slide due to the deformation resistance of the wires and the wire protector caused by the movement of the slide is reduced, and appropriate movement of the slide is ensured.

Component mounting machine

There is provided a screen printer including: a squeegee device for spreading a cream solder over a mask having formed thereon a printing pattern configured of a plurality of through holes to force the cream solder through the printing pattern; a clamping device for holding a board that is conveyed to be placed under the mask; and a lift device for disposing the board with respect to the mask in relation to a vertical direction, wherein the clamping device includes a pair of clamping portions for holding the board therebetween from a width direction, wherein the pair of clamping portions includes individually detachable clamping members that are brought into abutment with lateral end faces of the board, and wherein the clamping members individually have two or more clamping surfaces that are brought into abutment with the board in such a way that the clamping surfaces can be converted.

Screen printer

A mounter capable of curtailing interference between a mounting head that has a component holding section, and an exchange-use component holding section and a storage section that holds the exchange-use component holding section. A controller of the mounter reads head identification information for identifying the mounting head from the mounting head. Also, different quantities of protruding sections are formed on nozzle tray in accordance with the height in the Z-axis direction. Also, pressure switches that are pressed by protruding sections so as to turn on and off are provided on loading plate on which nozzle tray is loaded. By this, the controller is able to determine whether interference will occur between the mounting head and nozzle tray based on the detection signal of the pressure switches before the mounting head is moved.

Mounter

A solder supply device provided with a solder cup housing liquid solder that is tubular and open at one end; a nozzle section, for ejecting solder from the solder container, that is inserted into the solder container; a flange section that is provided on an outer circumferential section of the nozzle section and that is engaged inside of the solder cup; and an outer tube that demarcates an air chamber with the bottom surface of the solder cup. Solder is supplied from the tip of the nozzle section by the solder cup and the flange section being relatively moved by supplying air to the air chamber. Solder is supplied from the solder container without using an air cylinder, electromagnetic motor, or the like.

A solder supply system that judges whether a solder cup is set on a solder supply device. In a case in which it is judged that the solder cup is set on the solder supply device, reading a barcode by a barcode reader is allowed. In contrast, in a case in which it is judged that the solder cup is not set on the solder supply device, reading a barcode by the barcode reader is restricted. That is, reading a barcode by the barcode reader before the solder cup is set inside an outer tube is restricted, while reading a barcode by the barcode reader is allowed when the solder container is set inside the outer tube.

Based on the positions of the magnet and the sensor, the post-movement position of the solder container is detected. Thus, it can be detected that solder has run out from inside the solder cup.

Solder supply device including a sensor to detect movement of a solder container

A screen printing machine configured to move a squeegee by a squeegee moving device along a mask to print solder on a substrate through a through hole of the mask is improved in size and usability. A squeegee-device main body is fixed to a mask frame receiver for holding a mask frame, and a squeegee slide, a squeegee head, and a squeegee-slide driving device are provided on the main body. A position adjusting device including two front/rear-direction adjusting units, one right/left-direction adjusting unit, and one floating support unit is provided between a main body frame of the screen printing machine, and the mask frame receiver and the squeegee-device main body to adjust relative positions of the mask and the substrate by moving the mask frame receiver and the squeegee-device main body together with each other.
